A new brainteaser may help you determine if you're a genius - but you must figure it out in less than 20 seconds.
Not only are they a great way to keep you entertained, but regularly completing puzzles are a great way to keep your memory strong. So, if you want to keep busy while giving your brain a mental workout, why not give this optical illusion a go?
Shared by JagranJosh.com, the animation displays a bunch of dartboards and takers must spot the one with different coloured darts. However, like most optical illusions, it's trickier than it sounds.
The boards are mostly black, but also contain red markings and are also against a ruby background, making finding the red darts all the tougher to spot. Those who have all the time in the world will no doubt be able to figure out, but the real challenge lies in how fast it can be done.
It is said those who can complete this optical illusion in 15 seconds or less may have a "genius IQ", reports the Mirror.
